Initial Start-Up

3.1 Inserting Batteries or Rechargeable Batteries

Be certain to refer to section 9.2 regarding correct battery
installation.
Momentary battery voltage can be queried in the Info menu (see
section 6.3).
!
Attention!
Disconnect the instrument from the measuring circuit before open-
ing the battery compartment lid in order to replace the batteries.
Operation With Power Pack (not included, see section 10.3)
Installed batteries are disconnected electronically if the NA X-TRA
power pack is used, and need not be removed from the instru-
ment. If rechargeable batteries are used, they must be recharged
externally.
If the external power supply is switched off, the device is switched
to battery operation without interruption.

3.2 Switching the Instrument On

Switching the Instrument On Manually
Ð Press the ON / OFF | LIGHT key until the display appears.
Power-up is acknowledged with a brief acoustic signal. As
long as the key is held depressed, all of the segments at the
liquid crystal display (LCD) are illuminated.
The LCD is depicted on page 11.
The instrument is ready for use as soon as the key is released.

Display Illumination
After the instrument has been switched on, background illumina-
tion can be activated by briefly pressing the ON / OFF | LIGHT key.
Illumination is switched back off by once again pressing the same
key, or automatically after approximately 1 minute. If necessary,
automatic deactivation of background illumination can be disab-
led with the appropriate parameter setting (see bLiGht parameter
in SYStEM submenu) or via the interface.
Switching the Instrument On with a PC
The multimeter is switched on after transmission of a data block
from the PC, assuming that the "irStb" parameter has been set to
"on" (see section 6.4).
However, we recommend using the power saving mode: "off".
Note
Electrical discharge and high frequency interference may
cause incorrect displays to appear, and may disable the
measuring sequence.
Disconnect the device from the measuring circuit. Switch the
instrument off and back on again in order to reset. If the
problem persists, briefly dislodge the battery from the con-
nector contacts (see also section 9.2).
